Definitions
- This invention relates to polyamidopolyamines. More particularly, this invention relates to polyamidopolyamines prepared by reacting an aliphatic or an aromatic di-primary amine with the carboxy terminated reaction product of a poly(oxyethylene/oxypropylene) diamine or triamine with at least a bimolecular molar excess of an aromatic or aliphatic dicarboxylic acid, ester or anhydride thereof.
- this invention relates to novel polyamidopolyamines prepared by reacting at least two mole equivalents of a polyoxypropylene, a polyoxyethylene or a poly(oxypropylene/oxyethylene) diamine or triamine with an aromatic or aliphatic dicarboxylic acid to form a carboxy terminated intermediate product which is then reacted with an equimolar amount of an aliphatic or aromatic di-primary amine to thereby provide a polyamidopolyamine characterized by the presence of terminal primary amine groups and internal amido and carboxyl groups.
- the reactions are preferably conducted at autogenous pressure at temperatures within the range of about 150° to 250°C.
- the polyamidopolyamines of the present invention are liquids or amorphous solids, depending upon the starting materials, and can be used as raw materials for a wide variety of purposes such as, for example, as chain extenders for epoxy resins, curing agents for epoxy resins, as raw materials for the manufacture of polyureas, thickening agents, etc.
- the products may also be used as raw materials for the preparation of fuel and lubricant additives, for textile and fiber treating agents, for the preparation of adhesives, for use in the manufacture of polyureas, for use in encapsulation and molding applications, etc.
- polyoxyalkylene polyamines by the reductive amination of a polyoxyalkylene polyol.
- the reductive amination is conducted catalytically in the presence of hydrogen and ammonia and an appropriate reductive amination catalyst, such as a nickel, copper and chromia catalyst.
- an appropriate reductive amination catalyst such as a nickel, copper and chromia catalyst.
- the polyoxyalkylene polyamines that are prepared in this fashion are stable articles of commerce having a wide variety of uses such as those mentioned above. In particular, they have found utility as curing agents for epoxy resins, as plasticizers, as cross linking agents and binders for textiles, and as intermediates in the preparation of polyureas.
- polyoxyalkylene polyamines having molecular weights ranging from about 200 to about 5,000 can be prepared by the Yeakey process.
- Kwang U. S. Patent No. 3,257,342 is directed to epoxy resins that are cured with a polyamidodiamine prepared by reacting about two molar equivalents of a polyoxyalkylenediamine with an aliphatic dicarboxylic acid.
- Klein U. S. Patent No. 4,133,803 is directed to the preparation of novel thermoplastic adhesive compositions having melting points between 20° and 180°C prepared by reacting a polyoxypropylene diamine or triamine with an aliphatic or aromatic dicarboxylic acid, ester or anhydride thereof.
- Klein used approximately equimolar amounts of carboxylic acid and polyamine. However, he states that the molar ratio of the polyoxypropylene diamine or triamine to the dicarboxylic acid may range from about 0.25:1 to about 4.0:1.
- the thermoplastic adhesives of Klein are made by reacting the polyoxypropylene diamine or triamine with the dicarboxylic acid at about 175° to about 275°C for about 1 to 12 hours.
- thermoplastic adhesives The preparation of thermoplastic adhesives is disclosed in Schulze U. S. Patent No. 4,119,615.
- the adhesives are prepared by a two-step process. In the first step, about 1 to 4 moles of oxalic acid is reacted with a polyoxyalkylene diamine or triamine, the preferred ratio being a mole ratio of about 1 to 2 moles of oxalic acid per mole of polyoxyalkylene diamine or triamine.
- This results in the formation of a so-called liquid prepolymer which is then reacted with an alkylene diamine such as ethylene diamine which contain 2 to 18 carbon atoms to provide the resinous polyoxyamide thermoplastic adhesive composition.
- Mains et al. U. S. Patent No. 4,062,819 is directed to polyamide polyblends wherein one component is a high molecular weight thermoplastic polyamide and the other is a minor amount of a polyamide derived from a high molecular weight dibasic acid.
- the second component is prepared by reacting a dicarboxylic acid such as "dimer acids" with an aliphatic polyalkylene diamine such as ethylene diamine.
- Rasmussen U. S. Patent No. 4,218,351 discloses impact resistant thermoplastic polyamides which are suitable for use as hot melt adhesives and which contain, as a component, a minor amount of an amorphous amide-forming oligomer which is described as a polyoxyalkylene diamine having a number average molecular weight in the range of about 900 to about 5000.
- Rieder U. S. Patent No. 4,239,635 is directed to aqueous metal working fluids containing a carboxylic acid group terminated polyoxyalkylene diamide or an alkali metal, ammonium or organic amine salt of the diamide.
- the diamide is prepared by reacting a dicarboxylic acid with a polyoxyalkylenediamine in a 2:1 mole ratio.
- Chang U. S. Patent No. 4,588,783 relates to heat curable compositions containing polyhydroxyethyl carbonates which are prepared by reacting an amidoamine with an organic carbonate.
- the amidoamines are prepared by reacting a polyester with an equivalent excess of a polyamine, for example, by reacting two moles of isophorone diamine with one mole of dimethylcyclohexane dicarboxylate.
- the polyoxyalkylene polyamines of the type disclosed in Yeakey U. S. Patent No. 3,654,370 are prepared by the oxyalkylation of a polyhydric alcohol.
- the preferred starting materials are dihydric and trihydric alcohols such as propylene glycol or glycerol and propylene oxide or ethylene oxide.
- Copolymer polyols of ethylene oxide and propylene oxide are also useful, particularly those containing from about 5 to about 40 wt.% of ethylene oxide and, correspondingly, from about 95 to about 60 wt.% of propylene oxide.
- the molecular weight of the polyol is determined by the number of moles of epoxide that are reacted with the alcohol initiator. Since the addition is random, the final alkoxylation product will not be a pure compound but, rather, will be a mixture of polyoxyalkylene polyols.
- the polyol is a polyol prepared by reacting glycerol or trimethylol propane with propylene oxide, using an amount of propylene oxide adequate to provide for an average molecular weight of about 1,000, the final propoxylation product will actually be composed of a mixture of polyoxypropylene triols having molecular weights varying from about 800 to about 1,200, the molecular weight distribution following a Gaussian distribution curve (sometimes referred to as a sine curve or a Poissan curve). As the molecular weight of the polyol increases, the spread in the molecular weights will also increase. Thus, when the average molecular weight of the triol is about 3,000, the deviation will be about ⁇ 400 molecular weight units so that most of the product will fall within the molecular weight range of about 2,600 to about 3,400.
- a Gaussian distribution curve sometimes referred to as a sine curve or a Poissan curve
- the percentage of free hydroxyl groups in the reaction mixture will decrease because of the added bulk of the already formed polyol, thus making the addition of more propylene oxide groups progressively more difficult.
- the triol reaches an average molecular weight of about 5,000, further propoxylation is accomplished only with extreme difficulty.
- the 5,000 molecular weight polyoxypropylene triols will have a molecular weight distribution of about ⁇ 1,000 so that the actual molecular weight range will be from about 4,000 to about 6,000. Again, the molecular weight distribution following a Gaussian distribution curve.
- a further complication is encountered during the propoxylation to the higher molecular weights.
- the reaction time and temperature are increased to encourage propoxylation, there is introduced a tendency on the part of the propylene oxide to isomerize to allyl alcohol and a tendency on the part of the hydroxypropyl end groups of the polyoxypropylene triol to dehydrate to form a terminal olefin group and water.
- Both the water and the allyl alcohol are susceptible to oxyalkylation thereby diluting the polyoxypropylene diol with undesired generally low molecular weight diol contaminants derived from the water and monofunctional allyl alcohol propoxylates. From as little as one percent to as much as ten percent of the oxypropyl end groups of the triol may dehydrate to form groups with terminal unsaturation in increasing the average molecular weight from about 3,000 to about 5,000.
- molecular weight distribution and terminal unsaturation problems such as those mentioned above are significantly reduced through the provision of aromatic amidoamines containing terminal primary amine groups which are analogous in function and reactivity to the polyoxyalkylene polyamines of Yeakey et al.
- Another significant property of the aromatic amidoamides of the present invention is the desirable increase in "stiffners” or "hardners” that is obtained without otherwise adversely affecting the other properties of the amidoamines.
- the resultant cured epoxy resin will frequently exhibit undesirable flex and impact properties and other related properties attributable to the "rubbery" nature of the high molecular weight polyoxyalkylene polyamines.
- additives and/or fillers to provide a final cured epoxy resin having the desired physical properties.
- aromatic amidoamides of the present invention being significantly stiffer, can be used successfully with lesser quantities of fillers and/or additives or even without additives.
- the addition of these amide groups adds phase mixing advantages (when used as epoxy curing agents) over conventional polyoxyalkylene polyamines in many situations.
- the improvements of the present invention are obtained through the provision of novel polyamidopolyamines which are prepared by the sequential reaction of an aliphatic or aromatic di-primary amine with a reaction product of at least a bimolecular excess of an aromatic or aliphatic dicarboxylic acid with a polyoxyethylene, a polyoxypropylene or a poly(oxyethylene/oxypropylene) diamine or triamine.
- the intermediate reaction products of the present invention are obtained by reacting a polyoxypropylene, a polyoxyethylene or a polyoxypropylene/polyoxyethylene diamine or triamine with an aliphatic or aromatic dicarboxylic acid in molar proportions such that at least about 2 mole equivalents of carboxylic acid are provided in the reaction mixture for each mole equivalent of amine present in the reaction mixture.
- each of the primary amine groups of the polyamine will preferentially react with a carboxyl group of the carboxylic acid, ester or anhydride thereof and be linked thereto through an amide linkage to thereby provide a reaction product which is substantially free from terminal primary amine groups and is characterized by the presence of terminal carboxylic acid, anhydride or ester groups.
- the reaction between the polyoxyalkylene polyamine and the aromatic carboxylic acid, ester or anhydride thereof is preferably conducted in an autoclave at autogenous pressure which may suitably range from about 0 to about 1 atmospheres and at a temperature of from about 150° to about 250°C.
- autogenous pressure which may suitably range from about 0 to about 1 atmospheres and at a temperature of from about 150° to about 250°C.
- the reaction time required for completion of the reaction will normally range from about 0.5 to about 12 hours.
- By-product water of reaction is preferably removed as formed, so that the reaction product obtained at the end of the reaction is the desired final product.
- the thus-prepared intermediate reaction product is then reacted under essentially the same conditions outlined above with an aliphatic or aromatic di-primary amine to form the polyamidopolyamine reaction products of the present invention which are characterized by the presence of terminal primary amine groups, the substantial absence of terminal carboxyl groups, and the presence of internal amido and carboxy groups.
